You may need to use the appropriate technology to answer this question.

Use the sample data below to test the hypotheses

H0: p1 = p2 = p3
Ha: not all population proportions are equal

where

pi

is the population proportion of Yes responses for population i.

Response Populations
1 2 3
Yes 145 145 106
No 95 145 114

Find the value of the test statistic. (Round your answer to three decimal places.)

Find the p-value. (Round your answer to four decimal places.)

p-value =

Using a 0.05 level of significance, state your conclusion.

Do not reject H0. We conclude that not all population proportions are equal.Do not reject H0. We cannot conclude that not all population proportions are equal.    Reject H0. We conclude that not all population proportions are equal.Reject H0. We cannot conclude that not all population proportions are equal.
